Battery Maintenance


(1) Keep the outer surface of the battery clean and dry, remove the oxides on the pole and cable clip in time, and ensure that the cables on the pole of the battery are firmly connected.

When cleaning the battery, it is best to remove the battery from the car, rinse the entire shell with soda solution, and then rinse the battery with water, dry with paper towels. For battery supports, scrape thick corrosive materials with a putty knife, clean the supports with a soda solution, and then rinse and dry them with water. After the support is dry, apply anti-corrosion paint.

Poles and cable clips can be cleaned first with soda water and then with a special cleaning tool. After cleaning the cable clip, apply vaseline or lubricating oil to prevent corrosion.

Note: Before cleaning the battery, tighten the filling hole cover to prevent soda water from entering the battery.

(2) Keep the vent on the filling hole cover unblocked and dredge it regularly.

(3) Check and adjust the electrolyte level regularly. If water is insufficient, add distilled water.

(4) When the car runs 1000 km or 5-6 days in summer and 10-15 days in winter, the density meter or high speed flowmeter should be used to check the storage once.

Discharge level of the battery. When the discharge exceeds 25% in winter and 50% in summer, the battery should be removed from the car in time for supplementary charging.

(5) Timely adjust the density of electrolyte according to seasonal and regional changes. In winter, an appropriate amount of electrolyte can be added, with a density of 1.40g/cm3.

Increase electrolyte density (generally 0.02~0.04g/cm3 higher than in summer).

(6) When adding distilled water to the battery in winter, it must be carried out before charging the battery to avoid uneven mixing of water and electrolyte, which may cause icing.

(7) The battery should always be fully charged in winter to prevent the electrolyte density from falling and freezing, resulting in shell cracking, plate bending, and active substances falling off.
